Application March 8, 1949, Serial No. 80,188 'In Italy January 12, 1949-2;Cla'ir ns. 1 The present invention relates to a device forwater-spouts in ornamental forms which allows the embodiment ofwater-works having decorative character, which may be easily applied tothe sprayers for fields, plantbeds, garden founso as to embody betweenthe two substantially frusto-con-ical shapes which confer to thewaterspout under pressure which enters the device, a conoidal shape ofdifferent inclination according to the thickness of the out-flowingwater and of its pressure.

The thickness of the out-flowing water between the various elements ofthe device .may be controlled by nearing or diverting the very elements;same control .may be operated so .as to obtain the water out-flowingrather than in a continuous shape, with a fine sprays-enevelope, whichresults in a very particularly esthetic effect.

The device is preferably composed by more elements screwed in oneanother, and allows the embodiment of as many-blades as are the conoidalshapes comprised between the elements.

In order to diminish the number of waterblades out-flowing, it issufficient to tightlyscrew, among themselves, the two elements whichdefine the water-blade to be abolished.

Finally, over the superior element is provided a central spout obtainedthrough a stopper which by being screwed in the very element, allows thecontrol or the obstruction of the spout.

In order to confer to the water-blades which out-flow from the devicethe required effect, the various shapes between the elements formfrustocones each of which become flatter progressively from top tobottoms,

In order to allow the passage of water when the conical surfaces are incontact, water chambers are provided between the central zones of saidsurfaces.

A preferred form of embodiment of the invention is illustrated in theattached drawings, in which:

Fig. 1 shows a lateral elevation of the device;

Fig. '2 shows a vertical *diametral section "of the device;

Figs. 3 and '4 show the plan views of two elements composing the device,and

Figs. 5, 6 and 7 show some 'forms of water- "works obtainable throughthe "device.

With reference 'to drawings:

The device is embodied by a, series of elements screwed within oneanother and particularly by an inferior element I, substantiallycylindrical, through which the water is fed to the device. Element I hasin its lower part a thread 2 for the connection to the water plug to beused and in its central position a hole '3 with fthread inwhich can bescrewed the shank 4, which is also threaded, of the upper element,

The superior surface of the "element I and the inferior one of theelement fi, presentfacing-each other, two-zones constituted by annulusof equal surface. Externally to said zones and connected to them, aretwo conical zones 5 and 7 which give the shape to the out-flowing water.

The water, which enters from the lower part of element I, rises alongthe annular row of cylindrical conducts 8 surrounding the threaded hole'3 so as to arrive between the upper disc of element 1 and the lowerdisc of element 5; from here the water comes out under the shape of acontinuous blade or of an envelope of sprays.

Element 5 is surmounted by the substantially analogous element 9, whichthrough the threaded shank I0 is screwed in the threaded shank 4 ofelement 5.

When the zones 6 and I are in contact, a water chamber 25 is formedbetween said discs.

Also elements 5 and 9 present, facing each other two annulus surroundedby the conical Surfaces l I and I2 which in their turn define the upperwater-blade.

Elements 5 and 9 are pierced by a plurality of vertical conducts I3 andI4' surrounding the threaded shanks of the elements and able to adduceto the upper annulus of each of the elements, the water fed to thedevice from the lower inletting opening.

In the central shank ID of element 9 is screwed the central shank whichis also threaded, I5, of the element I 6;

The elements I5 and I6 repeat the embodiment afore described, and havetwo facing annulus, surrounded by the conical surfaces I I and I8, so asto produce the third upper blade, of the water out-flowing from thedevice.

Also element I6 is pierced by the vertical conducts I9 which arrive toits upper disc 20'.

Around the disc 20, is provided a sleeve 2| internally threaded in whichcan be screwed the stopper 22, substantially cylindrical and pierced bythe axial conduct 23.

The stopper 22 is provided with two little projections 24 for thefitting of the key, for screwing and unscrewing it, in order to obstructmore or less the conduct 23.

When the elements are fully screwed in one another, the water fed to thedevice finds no exit.

When, for instance, element 5 is unscrewed so as to create a passagebetween the conical elements 6 and I, the water passing through theconducts flows out in the shape of a continuous cone through saidelements.

The situation is repeated analogously for the upper passages definedrespectively by the conical elements I|l2 and "-18.

The central spout is produced through hole 23 only when the stopper 22is distanced from disc 20 allowing the passage to the water throughconducts 19.

Figs. from to '7 show merely by way of example, some of the shapes ofthe water works according to: (1) the number of passages open to theout-flow of the water; (2) their thickness and to the greater or smallerpressure of the water fed to the device, which pressure can be operatedby means of a valve away from the device and has nothing in common withit.

Particularly Fig. 5 shows the case where only one of the conicalpassages is open, whilst Figs. 6 and '7 show two Water works with twoconical passages; that shown in Fig. 6 has the central spout which ismissing in the case of Fig. 7.

As every shape of the out-flowing water blade, owing to a constantfeeding pressure, to the device, corresponds to a particularfixed-position of the various elements constituting the device, variouspositions indicating different water patterns may be indicatedexternally on the device to facilitate adjustment.

I claim:

1. A water Works spray device adapted to emit sprays of varying shapescomprising, in combination, a cylindrical body threaded for connectionwith the water line and having an innerly- 4 threaded bore portion, aplurality of cylindrical cup-shaped elements interconnected insuperposed relationship by adjustable threaded engagement, said elementsincluding a lower element, an upper element, and at least oneintermediate element, each of said elements having a threaded bore and athreaded cylindrical projection engageable in the threaded bore of thenext subjacent element, the projection of the lower element beingengageable in the threaded bore portion of said body, said body, saidlower element and said intermediate element having a peripheral inwardlyinclined zone in which is received the base portion of the nextsuperposed element and an axial recess defining an open space betweensaid body and said elements, axial ducts extending through said body andsaid elements, the axial ducts of said body and said lower andintermediate elements extending into the respective axial recesses, andan axially-bored stopper threadedly engaged with the threaded bore ofsaid upper lement to restrict the flow of water from the axial ducts ofsaid upper element.

2. A device according to claim 1, wherein the inwardly inclined zoneshave a gradually decreasing angle of inclination in progression from thebody to the upper element.
